Title: Windscreen wiper for rectangular area - with parallel link levers on reciprocating band drive carried on spaced drive wheels
Inventor: RECH HELMUT DIPL ING DR
IPC: B60S1/24
Filed: 1974-10-15
Abstract: The windscreen wiper arm (34) is linked to two parallel link arms (30, 31) which are themselves fitted to drive wheels (50, 52) of an endless band drive (51), with the spacing of the wheels equal to the spacing of the attachment points of the link arms on the wiper arm. The outer wheel (50) has a gear wheel (40) fitted to it to mesh with a gearing segment (41) which is fixed. The endless belt drive thus sweeps over the gearing segment while at the same time altering the relative angle of the link arms with the belt drive axis. This alters the effective length of the wiper arm, w.r.t. its pivot point, and enables the wiper blade to reach into the upper corners of the rectangular windscreen.

Title: Wind operated turbine for power production - has blades pivoted on pins to limit axial bending moments
Inventor: GOSLICH HANS-DIETRICH
IPC: F03D1/06
Filed: 1975-10-20
Abstract: Turbine horizontal shaft (2) mounted on the top of a tower, carries a number of blades (1) arranged circumferentially round it and attached to it by means of pins (3) which are in a plane perpendicular to the axis of the shaft. In normal operation centrifugal force on the baldes brings them into a position (1) perpendicular to the shaft. If the window force increases while the rotational speed is maintain constant by an appropriate control system the blades pivot about their pins into an inclined position (a). This prevents an increase in the bending moments due to wind force and the action thus automatically prevents overloads. Springs (4) between the blade pins (3) bring the blades back into the perpendicular position at standstill.

Title: Glaze-like phosphate coating on ceramic bodies - formed from aq. solns. contg. metal phosphates and opt. colouring agents and thickeners
Inventor: DORN KARLHEINZ DR RER NAT
IPC: B01J19/32
Filed: 1976-01-16
Abstract: Coatings are formed on ceramic bodies (raw, dried or burnt) by applying onto their surfaces an aq. solns. of alkali(ne earth) metal phosphates or other metal phosphates (pref. orthophosphates or condensed phosphates) drying and firing. The soln. may contain water-soluble inorganic cpds. of boron and/or silicon, and also thickness such as (carboxy)methyl cellulose, starch, dextrin etc. Colouring water-soluble or insoluble metal cpds. can be included. Coatings can be formed on ceramic tiles, plates, stones bricks etc. pref. made from the clay-feldspar-quartz system (including natural clay, kaolin, crushed stoneware etc). The phosphate ions react with ions of Al, Ca, Mg, Fe and Mn and insoluble phosphates are formed. The resulting anchoring effect (esp. in the case of polyphosphate ions) ensures firm adhesion of the coating after the drying and firing (600-1200 degrees C) operations. The coatings are not inferior to glazes, and yet their formation is much simpler. The viscosity of the aq. solns. can be adjusted as required using conventional thickeners.

Title: Microstrip coupling to slotted conductor - uses microstrip branches for power dividing to ensure optimum energy transfer
Inventor: WIESBECK WERNER DR ING
IPC: H01P5/10
Filed: 1976-02-25
Abstract: The coupling of a microstrip to a slotted conductor is made by placing them at right angles to each other, the division of power between the two sides of the conductor being achieved with a T-type junction or with a hybrid junction. The crossing points of the slotted conductor with the two branches of the microstrip are offset by a quarter wavelength. In practice, the couplings (10, 11) of the microstrip (5) prevent reflection by the inclusion of a balancing resistance (12) between the ends of leads (6, 7) of the microstrip. The 180 deg. phase difference between the two branches is due to a quarter-wavelength side (16), while in the mixer diode (2) of the waves are in phase for addition. The length of side (16) as well as the length of couplings (10, 11) determine the ratio of power flow in the two branches.

Title: Cable and warning tape laying plough - produces downwards sloping slot in side wall of cable trench for tape
Inventor: KAINDL JOHANN
IPC: H02G1/06
Filed: 1976-03-03
Abstract: The cable-laying plough lays both cable and the tape that warns of the presence of a cable at the same time - ie in the same work process. The tape warns of the presence of a cable beneath it during later earth works. The cable (4) is laid behind the cutting blade through a chute (3). The warning tape (8) is laid into a slot (5) cut into the side of the trench some way above the cable and sloping downwards to prevent the tape falling out. Since the tape is guaranteed to remain in the slot the cutting of a second precautionary slot is unnecessary.
